Sadly it seems very unfinished:
1. It seemed like the enemies are harmless and pose no threat, just push you around, get in the way and die when they touch you. I didn't know until the end that the game does keep track of you getting hit.
2. I only accidentally discovered that you can attack, there is no in-game hint about it, though I should've read the instructions I guess
3. White rectangles as exit area just scream "no texture" - you could've reused one of the existing sprites and edited it a bit if you were running out of time
4. You can hear mouse clicks in the voice recording :)
5. The sudden interruptions feel annoying when there are no enemies nearby and you're just exploring
Overall a very interesting concept, I don't think I've ever seen a game where you play as a ball lightning. The backgrounds are great, as well as character animations, and it was a good choice to have terrain change colors to match background. Voiceover was a nice touch, though it kinda stands out because the game doesn't have sounds otherwise.
I'm probably being very harsh here, but hopefully my feedback would be useful for your future projects. Good luck!
